Date/time picker standard?

Supposedly, HTML5 includes various date/time input types. But only Opera really supports them, though 开发者_JAVA技巧I've discovered Chrome has (very) limited support for them as well. Is this really an HTML5 standard? Do major browsers plan to support these input types ever?

(ignoring jQuery solutions to this problem, etc. I'm talking about browsers natively supporting date/time input types)

Yes, that is in the HTML5 Working Draft:

Hence, we would expect the major browsers to support them in the future.
